Now that selftests/x86 uses the kselftest infrastructure, the
run_x86_tests.sh mechanism is just in the way.

Include lib.mk and set TEST_PROGS where appropriate.

Using uname with the processor flag option in some cases can yield 'unknown'
so lets use the machine flag option as it is deterministic. Add a dependency
for all_32 when building on a x86 64 bit host so that both bitnesses are
built in this case.

This is a very simple test that makes system calls with TF set.
This test currently fails when running the 32-bit build on a
64-bit kernel on an Intel CPU. This bug will be fixed by the
next commit.

This is my sigreturn test, added mostly unchanged from its old
home. It exercises the sigreturn(2) syscall, specifically
focusing on its interactions with various IRET corner cases.
It tests for correct behavior in several areas that were
historically dangerously buggy. For example, it exercises espfix
on kernels of both bitnesses under various conditions, and it
contains testcases for several now-fixed bugs in IRET error
handling.
If you run it on older kernels without the fixes, your system will
crash. It probably won't eat your data in the process.
There is no released kernel on which the sigreturn_64 test will
pass, but it passes on tip:x86/asm.
I plan to switch to lib.mk for Linux 4.2.
I'm not using the ksft_ helpers at all yet. I can do that later.
